Abstract (en)
[origin: WO2010087775A1] An actuator comprising a motor (1) having a drive shaft (2), a spindle (6) which is directly or indirectly driven by the drive shaft and which exhibits an axial recess being delimited by an internal limiting surface (34), said spindle comprising an internal thread (7) arranged on the limiting surface, said thread having a predetermined axial extension (1 1), and a piston rod (9) which is arranged in the recess to perform a translational movement relative to the spindle between a first end position and a second end position when the spindle is rotating, said end positions defining a length of stroke (1 2) of the piston rod, said piston rod comprising a threaded portion (11) which exhibits an external thread (30) and has a predetermined axial extension (1 3), said external thread (30) being adapted to interact with the internal thread of the spindle. According to the invention, the axial extension (1 1) of the internal thread (7) of the spindle (6) is at least twice as long as the axial extension (1 3) of the threaded portion (11) of the piston rod (9).
